A piece of gum which weighs 62.7 g is stuck to the ceiling of a train car (we call this adhesion force) and the train is accelerating towards the right at a height of 6.25 m/s .the gum does not fall and does not slide on the ceiling during the acceleration . 1. Find the nature of the force between the gum and the ceiling that propulses the gum with the train.indicate its type ,size and direction 2. for the same situation ,if the adhesive force between the gum and the ceiling is 1.415 N ,find the friction coefficient .
